' To @ZZ whom t may concern.'

i Be it known that I, FnANois W. DOLIER, citizen of the United States,residing at Moorestown, in the county of Burlington and State of NewJersey, have invented certain new and useful improvements in Pencils, ofwhich the following is a specification.

rlhis invention relates to pencils and writing equipment and pertainsparticularly to a transparent outer casing or sleeve mounted on thebarrel of pencils and pens.

One of the objects of the invention is to provide a pen or pencil havingeither a decorated barrel portion which is protected by an outertransparent sleeve or which has an intermediate decorated sheet of thinmaterial inserted between the barrel and the outer transparent sleeve.,The decoration on the barrel or sheet might be either a name andaddress or some advertising data.

One feature of the invention relates to the combination with magazinepencils having one or both ends removable, thus facilitating themounting of the transparent sleevepon the barrel and the positioning ofthe sleeve by a removable end. This application was divided fromapplication Serial Number 510,492, filed October 26, 1921, since issuedas Patent 1,436,581, NovemberV 21, 1922, which was directed to aA pencilof a type particularly adapted for use with the sleeve of the presentinvention.

The particular conguration and relative position of the parts is setforth in conjunction with a mechanical pencil of a desirable type in thefollowing specification and claims, and illustrated in the accompanyingdrawing in which: f Y

Fig. 1 is an enlargedl view of a section taken centrally andlongitudinally through the transparent sleeve and intermediate sheetbetween the sleeve andthe barrel of the pencil;

Fig. 2 is a side view of the unitary combined actuated screw andplunger, as removed from the pencil;

Fig. 3 represents an end view of the barrel of the pencil, showing theouter sleeve, the intermediate sheet, the barrel and actuated screw andplunger in position within the barrel and the plungerl within thecentral tube; and

Fig. 4 represents an end view of the actuating end piece, with theeraser removed, and illustrating the position in which the extremerearend of theactuating spring screw member is. secured to the actu atingend piece. i

Referring in detail to the drawing, 1 indicates the barrel of a pencilof the type described, enlarged considerably in Aorder to more clearlyshow the relative positionsv of the parts. 1a indicates the rear end ofthe barrel and 1h indicates the front end of the barrel, and these endsare provided `with the respective threaded outer portions 1c and 1?.Screw threaded to the end v1a is a rear end cap 2 having screw threadsV2a onthe inner surface thereof engaging the threads 1c of the barrel.The rear face of the cap 2 is indicated at 2b, and centrally through ythis rear face is an opening 2,?, the pjurpose of which will bedescribed. The opposite end of the cap 2 provides a first annularshoulder or flange'surface -21having a thickness the same as the wall ofthe cap for cooperation with the sleeve, as will be described. The frontend is provided with a screw threaded fastening cap 3 which has a rearportion 3 with threads adapted to engage the threads 1d ofthe barrel.Tapering forwardly from the portion 3a, the inner walls of the tipareiin'dicated at 3b and this tapered portion extends into a moresharply inclined part indicated at 3C. ,The

rear end of the cap is also pro-vided with the square cut .shoulder orannular flange surface indicated at Bd'corresponding to the shoulder 2dof the rear end cap and which cooperates with the sleeve, as will bedescribed. indicated at Se and a restricted bore for providing a tightsliding fit for the lead is indicated at 3f. Between the points 3 andthe bore 3f, there is provided a cylindrical portion having the walls 3gwhichqprovides a loose sliding fit for thecentral guide tubey as will bedescribed. Between the walls 3g and immediately adjacent the entrance tothe bore 3f is the `annular inclined surface 3h The extreme tip ofthevpencil is ,y

against which the central' tubeis adapted to rest in order to positionthe tube'centrally and bring-the bore of the tubeinto alignment withthebore 3H f The transparent sleeve 4 of thelpresentinvention, ofCelluloid or other suitable matethickness as the width ofthe flanges, sothat l the assembled pencil may provide a smooth exterior. Between thebarrel l and the sleeve e there is inserted a sheet lfL of paper bearingsuitable advertising or decorative material t'or display through thecylinder el, or the sheet la may be discarded and designs for artisticeffect or advertising material may be carved on the outer surface of thebarrel l and thus made visible through the cylinder 4i althoughprotected trom actual wear by the outer transparent covering. Thematerial o1 the threaded ends lC and ld, in this case the barrel l,serves as means for holding the end means with their 'flanges 2 and 3din position adjacent the ends ot the transparent sleeve.

The operating mechanism of the pencil on which the sleeve ot' thepresent invent-ion is mounted will now be described. rit the extreme endof the pencil is the actuating end piece 5 which is formed, in thepencil illustrated, as a cylindrical cap having an end partition 5apositioned against the rear face 2b of the cap 2. The outer end of thecylinder 5 is turned inward or otherwise suitably provided with somegripping surtace as inl dicated at 5b to engage and hold an eraser. Thepartition 5a is provided with a central opening to be in alignment withand correspond to the openin(y 2C in the cap 2 for the reception of therear end of the actuatingl screw and the' securing` oit an end betweenthe plates 5c and in the space 5, as will be described.

A central partition 6 is securely fixed within the barrel by brazing,soldering or suitable means, and divides the inner bore ot the barrelinto a front and rear chamber, the front chamber being a n'iagazine torextra leads, and the rear chamber containing thc actuating screws. Thepartition 6 has an axial opening 6a for the reception ot' the guide tubeas will be described.

The guide tube 7 is als 'i rigidly mounted within the opening 6a ot thepartition 6 by brazing or soldering, and is thus fixed with respect tothe barrel. The tube 7 has the extreme front end 7a proj ecting beyondthe end of the barrel and adapted to engage the inclined wall 3h of thetip. The rear portion of the tube on the opposite side ot' the partition6 is indicated at 7b and is provided with a slot through the wallthereof at 7", this slot extending from the rear end ot' the guide tubesubstantially all or' the way to the partition.

The actuating helically coiled spring screw member 8 substantially lillsthe diameter of the bore of the barrel and extends the full length ofthe rear chamber. lit will be noted that the member 8 is free to revolvewithin the circular walls of the barrel; that the lateral port-ions ofthe springl 8 are loosely positioned Within the barrel, and that thecoils or turns of the member 8 are positioned apart a distancesubstantially as great as the cross section of the material ot thespring. rlhe extreme rear end 82L ot the member 8 extends through theopening 20 and is bent at right-angles lto the longitudinal axis ot thespring 8 and lined within the actuating end piece 5 by being soldered,brazed, or otherwise secured between the plates 5, which latter providethe space 5d having a width substantially the same as the width et theend 8a. in ll l the end 8 is illustrated as being continued through theopening 2 by an extension portion 8b, which latter is necessarilypositioned axially. yllhe opposite end of the member' 8 or the front endthereol is indicated at 8C, which end normally should be locatedrelatively close to the partition 6 so that the partition would preventthe actuated screw trom becoming untastened from the coils oit' thescrew 8.

yl`he combined actuated screw and plunger 9 is illustrated in itsremoved position in Fig. 2 and in its assembled position with the otherparts in Fig. l. rl`his structure is peculiar in that the plunger rod iscontinuous and formed in one piece with the actuated screw port-ion Qn.The member is inserted in the rear end ci? the barrel, when the cap 2and actuating piece 5 with thc actuating screw are removed, by fittingthe rod 9 into the slotted guide tube 7l. A right-angle shoulder 0bextends t'rom the straight rod Sl to the helical turn ot the actuatedscrew part 9a, this portion il" being illustrated in Fig. 3. Tl'ieright-angle shoulder 9b extends through the open slot 7 and ispreif'ented from turning by the walls ot this slotted opening. Comparingthe respective size and pitch of the turns of the helical screw portions8 and )EL as shown in Figs. l and 2, it will be noted that thesedimensions are substantially the same as may be compared by observingthe distance rfi-B in Fig. l with the distance C-D in Fig. 2. Referringto Fig. l it will be noted that the turn of the member 9a' substantiallylills the space between the adjacent turns ot the member 8.

The structure is assembled by first inserting a combined plunger 9 andactuated screw flu within the slotted tube so that the shoulder 9"extends tl'irough the slot. The rear cap 2 is then screwed into place bybringing the end 8C ot' the actuating screw into screw tl'ireadedengagement with the coils 9 and completing this turning movement untilthe end 8u is moved to its extreme position near the partition 6. Therear cap 2 is screwed into position on the threads 1c and soldered orbrazed to prevent turning. "lhe screw threaded portion may be so termedthat the binding ot the threads serves to hold the cap 2 :from turningwith resp ct to the barrel. rlhe actuating end piece .5 may then beturned with respect to the cap 2 in order to adjust theposition of theplunger 9 within the guide tube 7. Leads are normally inserted byremoving the front end cover 3 and slipping each additional lead as usedinto the front end of the tube 7, and then replacing the cap 3.Adjustment of the member 5 draws the plunger forward or backward, andthe lead is forced from the guide tube 7 through the bore 3f intoposition for use at the tip of the pencil 3e.

The arrangement of the yworking parts provides a resilient springlikeyielding movement to the lead which is most desirable in making for easywriting. The simplicity of the parts has provided an ineX- pensiveconstruction and one which is not subject to breakage or repeatedadjustments and the materials may be made from substantially any readilyWorked metal.

rIhe present invention requires that the transparent sleeve be held onthe pencil barrel and preferably this is effected by the use of membershaving flanges to hold the ends, at least one of which members isremovable. The invention may be used with any transparent material anda-substitution of any form of transparent material will not depart fromthe scope thereof.

I claim l. In a pencil, a barrel having a front end and a rear end, adetachable cap secured over said rear end and having the front end wallof said cap providing a first annular flange, the height of which flangebeing its thickness, a front end piece detachably secured over the frontend of said barrel and having the rear end wall of said front end pieceproviding a second annular iiange, the height of which is the thicknessthereof, and a removable transparent sleeve fitted endwise over saidbarrel and positioned between the adjacent end walls of said front endpiece and said rear' end cap and having a thickness of wallsubstantially the same as they projecting'height of said adjacent endwalls.
